Electric mini boiler rooms for heating a private house

Heating problems in a private home, cottage or garage can be easily solved using a device such as an electric boiler.

The equipment is easy to install, has many advantages and helps create comfortable indoor conditions.

Electric boilers come in different sizes: from large ones, which require a separate structure, to compact wall-mounted models that do not take up much space.

There is also such a modification as a mini-boiler. It is a compact module that can be installed in any closed heating system.

Types of electric mini-boilers

In fact, an electric boiler is installed wherever there is electricity.

It is important that the electric boiler is connected to existing heating systems (gas, solid fuel), reducing the load on them.

Installation will not require special permission . Mini-electric boilers are divided into two types according to the type of modification.

heating elements new

The water in the system is heated using the heating element of the electric boiler: heating element. Inside it is a spiral of tungsten or nichrome wire , which heats up and transfers heat to the environment. The shell is made of steel, titanium or aluminum. A dielectric is placed between the shell and the spiral . More often this role is played by quartz sand.

Main elements of the heating element mini-automatic:

heating element;
heat exchanger;
insulation;
Control block;
circulation pump.

Important! It is better to use distilled water in the heating system to prevent scale formation . This is the main “disease” of heating element boilers.

The device has an automatic switch that turns off the device when the desired temperature is reached or in case of overheating.

The power is constant and adjustable.
The temperature of the liquid does not affect the heating element.
If there are several heating elements, then if one breaks down, the device will work.
Various liquids are used as coolants : water, antifreeze, antifreeze.

If the heating element fails, it is replaced.
The formation of scale on the heating element is the main disadvantage of this device. Because of this, the boiler fails or heats up weakly.

Attention! During operation, the heating element must be covered with water, otherwise it will burn out !

Ionic

The operating principle of new generation ion electric boilers is different. They do not have a heating element, and the energy conductor is water or a special liquid.

Electrodes are placed here, passing through which the current heats the liquid. Ion boilers are also called electrode boilers . They heat up quickly, unlike heating elements.

The ion electric boiler has the following elements:

frame;
electrodes;
housing insulation;
Control block;
conductor of heat.

Some electric boiler models are equipped with a temperature sensor.

The system has built-in electronic control: when it cools down, the boiler will turn on itself, and when the desired temperature is reached, it will turn off. Works even with unstable voltage without turning off. Compared to a heating element boiler, an ionic boiler uses half as much electricity.

Installation of a mini boiler room

Installing a mini boiler room
The first thing you need to do before installing a mini boiler room is to read its instructions from start to finish. Especially the section that describes installation.

It’s not enough to just read what’s written there; you also need to do it all in practice.

Requirements for installing mini boiler rooms can be very different, for example:

Using a certain type of coolant, for example only water.
Connection via hydraulic separator (hydraulic arrow).
Requirements for pipeline sections.
Requirements for the room in which the heating device will be located.
If you want to use room thermostats or other automation, you first need to find out their compatibility.

In general, installing a mini boiler room should be easier and faster than installing a conventional electric boiler.

After all, you don’t have to connect the circulation pump, safety group and expansion tank. All this is already built into the design.

If the volume of the built-in expansion tank is not enough for a given system, you need to install an additional expansion tank.

Above I talked about installing a mini boiler room through a hydraulic separator (the second name for a hydraulic arrow).

It should be used if there is more than one circulation pump in the system. To understand why a hydraulic arrow is needed, follow this link.

Advantages and disadvantages of small horizontal electric boilers

Electric horizontal electric boilers are an excellent heating option for cottages, dachas, and private houses. They have their pros and cons.

Volatility: it is impossible to install the device away from the electrical network. If there are interruptions in the current supply, then there will be problems, as the equipment will simply fail.
Costs: More electricity consumption also means higher costs.
Scale formation: on models with heating elements, water scale forms over time, and the heating element must be replaced.

Device and features

The 220V heating equipment has a rectangular base with a control panel.

This explains the numerous advantages of the device: fairly compact size, absence of noise and smoke, as well as clear automated control of the unit on the front of the boiler. Two more advantages of the unit are the good quality and simplicity of the power circuit switches - starters, switches, etc.

An electric boiler is easy to install, since there is no need to create a special boiler room . The device is safe and environmentally friendly, as it does not emit combustion products harmful to humans.

As for the disadvantages of 220 V electric boilers, there are few of them: consumption of a large amount of electrical energy, scale formation on the heating elements.

In addition, in places where there is a problem with frequent power outages, it is better to install an uninterruptible power supply.

An electric heating boiler 220 V, in comparison with other heating devices, has one important feature: the presence of a heating element or electrodes:

A heating element is a nichrome spiral in electrically insulating packaging, located in a special aluminum tube. The heating element is attached to the bottom of the water tank, its leads come out. The big disadvantage of using an electric boiler with a heating element is corrosion of the tube coating.
The electrode heater is a two-blade equipment . A pair of electrodes are placed on an insulating base and attached to the bottom of the water tank. A current passes between the ends of the electrodes, which heats the water with high efficiency (more than 95%).

IMPORTANT!

The design of an electric boiler for heating a 220 V home also includes a control panel that ensures the safe operation of the device.

The electric boiler control unit contains:

various operating modes;
safety system in emergency situations (for example, when the coolant overheats or changes in pressure in the heating line.

Recommendations for choosing a new generation mini-automatic machine

In addition to the characteristics considered, it is worth paying attention to some more features:

Power - calculated individually for each type of boiler. The power determines whether the heating of the room will be sufficient.
Efficiency - for electric boilers, the efficiency factor is high - 95–98%.
Power adjustment can be stepped or smooth. In models with an independent heating element, step adjustment is used. Smooth is possible only in devices with a rheostat.
Price depends on many indicators: type of electric boiler (heating element, ionic), power, manufacturer, additional functions.

Reference! Particular attention should also be paid to the size, weight of the electric boiler, efficiency, and type of room that it will heat.

Innovative boilers "Scorpion"

These devices are a modern innovative Russian development in the field of electric water heating systems. Why are they so remarkable? Let's find out more about them.

Why is this type of electric boiler preferable?

Advantages over other electrical devices

The most important advantage of the Scorpion boiler is its efficiency. It uses electricity three to five times more economically than other electrical appliances.
Is unpretentious. The developers claim that it will work for years without your participation.
“Scorpio” has a compact size and operates silently.

How do they work?

Operating principles of the Scorpion device. These devices are of the electrode type. There are two electrodes inside, and liquid passes through them. Heating of the liquid is carried out due to the frequency of movement of the electrons, which are located between the electrodes.

How much electricity does it consume?

As mentioned above, the Scorpio boiler significantly reduces energy consumption, that is, three times less than other similar devices. For example, if we consider an ordinary brick house with an area of 100 m2 with a standard ceiling height of 2.7 -3 m, then electrical units consume 10 kW (according to standards 1 kW per 10 m2), innovative Scorpio boilers divide this figure by three. Thus, roughly speaking, this value will be equivalent to 3.3 kW.

In addition, you need to take into account the fact that Scorpio will not be in operating mode all the time. Since, having reached the desired temperature, it automatically turns off and turns on after a certain time, when the temperature in the radiators drops to 60 degrees. On average, the Scorpio boiler operates 12 hours a day, and 12 is in standby mode. Thus, this figure will further decrease to approximately 2.5 kW per hour.

How do Scorpio boilers help you save money?

Energy savings are achieved due to the high conversion rate of electrical energy into heat. This figure is three times higher than that of any other electrical appliance.

Do these boilers have a warranty?

Is a permit required to install Scorpio boilers?

This is an ordinary household appliance, so no permission is needed.

What is the power of Scorpio boilers?

This figure depends on the area of the house, it can be minimal - 300 W and maximum - 1 mW - this is a boiler room. For example, if you take the same area of 100 m2, you will need approximately 3.5 kW; for a house of 200 m2 you need a boiler of 7-8 kW.

At what price can you buy Scorpio boilers?

Thus, water heating connected to an electric boiler can not only be environmentally friendly, compact and attractive, but also, thanks to the latest developments, much more economical.
